Nothing is as fun as a warm pool in our own backyard as of lately. The boys are soaking it up and we are camping out all day next to the pool reading books and playing games. It is not quite warm enough out to use the hose to fill our cheapo plastic pool but a couple of large pots of super hot water can last a good couple of hours before a "warm-up" is requested. Little F is still getting the concept down that clothes and shoes are not required for bathing. What are you up too in your backyard for fun?
